This invention relates to oily compositions ing composition creeping extremely rapidly possessing pronounced penetrating and on the surface of any metal or of any comcreeping properties, and to methods of preparing the same. I have found that a composition having position containingmetals even in the oxidized form (e. g., on glass).

An illustrative example of compositions pronounced penetrating and creeping propembodying the present invention is the folerties and adapted for loosening adly lowing: rusted nuts, bolts, studs and other parts of machinery, may be prepared by admixing Per cent Kerosene, water-white a;

- he'aforesald acidic m xture 1--3 T Earafiine oil, having a viscosity of Considerable wpriation in the proportions of the ingredien s, and -in the ingredients altogether. For the kerosene there may with equal success be substituted a corresponding Saybolt 27-25 amount of Varnolene or other light, low

viscosity, petroleum distillate such as the furnace oil used in domestic oil-heating For the specific parafiin oil above identified there may be substituted another lubricating oil having a relatively high viscosity. Also, for the aforesaid acidic mixture there may, with substantially as good results, be substituted in .part other acidic mixtures obtained by the controlled, liquidydrocarbon mixtures with subsequent sepaor consist of a plulight hydrocarbon oil such s the distillate known as kerosene with a small amount of a parafiin oil of relatively higher viscosity about 150 at 1 than kerosene and a small amount of a nor- Th 1 d b mally liquid mixture consisting essentially e cPmposl Ion 15.5mm y P l 1 1 l of alifatic saturated carbox lic acids of necessary to combine the mgredlents Whlch I mineral origin substantially identical with are freely Soluble m each other" the acidic mixture obtainable by treating with aqueous alkali solution a reaction mass th 1 be d d V containing both saponifiable and unsaponiemse l l a f fiable components produced by the controlled from the Spmt of the mventlon', Thus liquid-phase partial oxidation of a petroleum the above f z the P P f the distillate known as 45 distillate, or fuel Pl 011 maredlsnt y dlmmlshed, oil distillate, or gasolines, or naphthenes, Y correspondmg Increase m h P p or other hydrocarbon mixtures consisting functlonfif essentially of hydrocarbons whose molecular Parafiin 9 {ngredlent to confer l weights are above those corresponding to 7 and lubrlcafimg Propertles P l f or 8 carbon to i th l l t l therefore, in cases wherelubrication Is not vated temperature and pressure in the presdesired the said ingredient may be omitted ence of an inciter of oxidation, separating aothe resulting soaps in solution from the unsaponified components, precipitating the soap acids from the solution, and subjecting the precipitated soap acids to distillation treatment at a temperature of from about l t 280 C. to about 300 C. whereby to obtain an acidic distillate fraction consisting essentially of' saturated alifatic carboxylic acids having an average molecular weight of from 160 to 165, and a rangeof carbon atoms in the molecule of from 4 to 12.

I claim: 1. A penetrating oil composition compr sing in major proportion a llglliTlOW-VlSCOSltY petroleumdistillate and a relatively small but effective amount of a normally liquid acidic mixture insoluble in water but freely soluble in said distillate and consisting essentially of ali'fatic saturated carboxylic acids, of mineral origin, having a range of carbon atoms in the molecule of from 4 to 12 and an average molecular weight of froml60 to 165.

2. penetrating oil composition comprising in major proportion a light low-viscosity petroleum distillate, in minor proportion a lubricating oil miscible with the said distillate, and a relatively small but effective amount of a normally liquid acidic mixture insoluble in water but freely soluble in said distillate and consisting essentially of alifatic saturatedcarboxylic acids, of mineral origin,- having a range of carbon atoms inthe molecule of'from 4 to 12 and an average molecular weight of from 160 to 165.

3. A penetrating oil composition as defined in claim 1, in which the petroleum distillate is kerosene. 1

4; A penetrating oil composition as defined in claim 2, in which the petroleum distillate is kerosene, the lubricatin oil is a 25 paraflin oil having a viscosity of a out 150 at 100 Saybolt, and in which the ingredients are present in about the proportion of 72% kerosene, 1 to 3% of the aforesaid acidic mixture, and 27 to 25% paraflin oil.

5. A penetrating oil composition compris ing in major proportion a light low-viscosity petroleum distillate and a relatively small but effective amount of a normally liquid acidic ,mixtureinsoluble in water but freely soluble in said distillate and consisting essentially'of alifatic saturated carboxylic acids, of mineral origin.

6. A penetrating oil composition as defined in claim 5, in which the petroleum distillate is kerosene.
